Jon Hamm, in all his bearded glory, is going to be coming to a television near you -- and not just in "Mad Men." The man behind Don Draper will be appearing on the April 18 episode of "Sesame Street," and an early look at his scene has been released.

In the above video, Hamm helps Elmo define the word of the day, "sculpture." Elmo is shown making a sculpture of his own, and he asks Hamm to show off other types of sculptures while he finishes the one he's making. Hamm brings out objects made of clay, marble and even metal, the last one causing him to fall over because of its weight. It's pretty adorable.

Hamm isn't the only big name to appear on "Sesame Street" this season. Other celeb guests include Melissa McCarthy, Donald Glover and Bobby Moynihan.
